Party requires game clear

• Tenshi main
  
• Marisa alt
  
• Chen - Never let the target get away level 100

Unfortunately I don't recall where I got this Chen card. If someone knows, feel free to leave it in the comments, I'll update the guide.

If you're a god gamer and are able to play on hard,
Then by beating Heaven 34 - Kagura 05 bonus objectives you can make this much easier

• Tenshi main
  
• Marisa alt
  
• Tenshi - Sweet Scent and Unyielding Tongue level 100 (ignore screenshot level)

You're allowed to miss 1 note. If you get lucky and a big note drops in the middle, then I'm not too sure how many notes you're able to miss. But that will give you some breathing room

You want to be very careful with your movement and hit all the notes. You need to hit as many of Tenshi's rocks as you can against the boss.
